To all it may Be it known that I,.HowLANo MAX E L HOWARD, a citizen of the United States, residing 'at Da'yton, in the county of Montgomery and State of Ohio, have inirented certain new a'nd' usefui Improvements in -Watermark1n Devices, of which the fol -l'owiug is'a 11, clear, and exact descrip- -tion.

This invention relates to water-marking devicesfor paper-and has for its object to providemechanism of such nature that the water-mark may. be applied to the paper during its ordinary process of manufacture h a paper machine, and al'soof such nature tliht the watermark design may be made up in any desired form by ordinary electro- ..t'ype or similar etal t-{Pc or designed ecn very o in H v -()b](tS of the invention, I will now proceed to describe the specific construction which plains. Of course it'has the .art to use metal type. in connection with water-marking ofpaper and the'use of ordinary elect-retype plates bearing the water-mark design has the obvious advantage that such plates are comparatively inex'enslve to make and very adaptable for quickly and conveniently changing the water-mark design as well as offering a .wide field of variation in the wording or in the pictorial representations that may be desired in the water-marks even to the extent of making useof very fine lines and I elaborate designs in the water-mark.

It has been very old in the art of water- 'marking paper, to have rollers bearing the water-marking design, and pressing them upon the-sheet of paper as it passes through the ordinary paper-making machine, so'as to-i1npress upon the paper .the watenmark design carried by the. rollers. It 'is' also very old'in' the art to locate these watermark rollers in proximity to the drying cylinders of; the machine, while the paper is still ina damp state, either before .or

after the web of paper has passed over a drying cylinder or cylinders, as may be found to givethe best results; and it is also old in the art in such machines as menhoned, to have the paper pass between the water-marking roller and another roller Specification of Letters Patent.

or design. u Mymvent-ion resides-in utilizing a particular kind of material for such cushiom ing'efiect as 'just above referred to, for the purpose ofsecuring more efiicient results, and it is also one of the purposes of the'invention do provide improved means 9f w 'mounting the water-marking rollers so that A convenient access may be had thereto and so' that they may be removed individually without interference one with the other; 1

also to provide novel constructions of the water-marking rollers themselves Boas to permit the convenient attachment and do; tachme'nt-of the. water-marking type suchnsmay be desired for impressing. on the pea/er or water-markingdesigns'.

it-h this general description of the main I have adopted, making-reference to the" drawings accompanying this specificationjs and showing a preferred form of embodi ment of my invention. l

In said drawings Figure 1 is aidi'agram matie view of the paper machine showing the ordinary rollers of any well-blown form of press such as the ordinary Fourdrinier paper-making machine, and also showing the location of my water-marking roller. Fig 1 is anenlarged detail view of a portion of the-fabricwhich -I utilize for covering the rollerbetween" which and the water-marking roller, the paper is fed. Fig. 2 is aneleva-t-ion view of a series of five oft-he water-marking rollers, one of the same being shown turned reparatory' to removal from its holdin yo e. 1 Figs. v3

and 4 show one of the yo es -for holding upon-by the roller containing the-pattern ture.

, which and'the drier 21 the 10 is a cross-secti0n ofthe water-marking is shown passing on to the first drier 21.

The usual felt band 22 is provided, between paper web passes. In proximity to this drier 21., is an impres- S101], roller, or what I may term a fabric roller, over which the paper web passes just before it reaches the first drier and against which presses the water-marking roller 31 carrying the water-marking design as hereinafter explained, This impression roller 30 is covered with a particular kind -of fabric wherein resides one part of my present in vention. The underlyingpart of the roller 30 may be of any substance suchas wood or metal as found desirable, but the roller is coated or inoased by a fabric 32 which forms a cushion for the web of paper to be pressed upon by the water-marking roller 31 carrying the water-mark design. And I have dis covered in a fabric of this sort there are particular advantages resulting from havin the outer surface of the fabric (over which the paper runs) of a smooth and glossy na- This'. glossy fabric surface I have found gives very good results in various ways as to speed of operation and fineness of design and asa preferred form 'of the fabric referred to I have adopted a material having a glossy surface finish similar to what is well .known as patent leather. But the particular material which I have found bestsuited for my purposes isa .japanned drill or duck material ,having a glazed smooth surface, of the sort well known on the market as manufactured by the Standard'Oil Cloth Company of New York city under the trade name of Meritas. Of course other fabrics having such glazed smooth surface might well be available for the purposes mentioned but I refer to this particular kind of fabric as a preferred form and one instance of a material which I have found givesvery satisfactory results. Of course the impression roller 30 might be entirely composed of such fabric as referred to with the outer surface thereof having the glazed smooth finish as ex plained. I desire also to point out that in the particular arrangement which I have adopted, this fabric 32 has both surfaces of this same glazed smooth 'finish, so that when the fabric incases the impression roller 30, the inner smooth surface of this fabric comes in contact with the surface of the underlying roller.

33 is an auxiliary roller which bears against the impression roller 30 so as to as; sist in keeping the fabric properly rolled out in shape, and to assist in removing any pos- 'place by means of overlapping to vthe fabric roller.

sible wrinkles just before the fabric passes under the paper.

Having thus described the general nature of the fabric'roller, I will now proceed to describe the water-marking roller and the means of mounting the same in proximity 40 indicates a wheel or roller, which is mounted to rotate upon a shaft 41. Collars 42 pinned to the shaft at each end of the hub limitthe end play of the roller. The ends of the shaft 41 are threaded to receive nuts 43. At one end the roller is provided with a shoulder 44 and at the other end a screw thread 45.- A band or sleeve 46 is made to slip on the roller and abut the shoulder 44. The inner e'nd of the sleeve 46 is provided with an overhanging bevel. A

sleeve 47 threaded to screw on to the thread 45 has a similar overhangingshoulder; it also has a recess 48 to receive a Spanner wrench, with which to screw up the sleeve.

Figs. 6 and 7 are views of a sector, having raised letters representing a design which is to appear upon the paper. Two of these sectors, which have beveled edges complementary to the overhanging bevels on the s ee es 46 and 47, may be laid around the relier and clamped in place by screwing the sieeve 47 againstthem. For certain purposes it may be desirable to set up the desired'word or words with separate type, in

which case individual type such as is shown in Fig. 8, also having bevel edges comple- .mentary to the bevels of the sleeves 46 and 47, may be used instead of the segments.

When the roller has been equipped with the printing device, it is mounted in a yoke 50, the shaft 41 lying in open slots 51 formed in the extremities of the yoke, the nuts 48 holding the shaft in place. The base of the yoke has an aperture 52 at each side of which are key-ways 53. The aperture is adapted to admit astud 54, which is secured to and forms part of the rock frame 55. A sta 'tionary shaft 60 is placed in suitable proximity to. the impression roll and upon, this shaft a succession of rock frames 50 are placed. The longitudinal position of each frame is adjustable and when adjusted,-

maintained by collars 61', which are held in place by set screws. A spline 62 is secured in one side of the shaft, which permits a limited rotary movement of the rock franfeythe key'way 56, which is formed in the rock frame, being somewhat broader than the spline. A stationary bar 65 has a number of guides 66, longitudinally movable on the bar and held in place byset screws. Each guide has an aperture through which a rod 67 passes freely, the rod having a fork at its lower end which embraces the arm 57, extending laterally from. the rock frame 55. The rod has a screw thread and a turn buckle 68' with which the tensionof a conipression spring 69 confined between the guide and theturn. buckle, may be adjusted. In Fig. 2, four rollers; mounted in yokes are shown in position for use. A fifthyoke' is shown detached' from but in position ready to e placed upon the stud 54. Itwill be observed that the yoke is turned one-fourth of the way around inattaching or detaching from the. stud, and by the time the yoke has. been pushed against the shoulder 58 the splines 59, carried by the stud 54:"will have emerged from the a erture 52, permitting the yoke' to be rotat obviously, the splines prevent the yoke slippin oil'- of the stud.

From the foregoing 'escription it is evident that the lateral position-of the rollers may be adjusted .to suit anyordinary rei -;'I amjaware that minor the parts of my invention while remaining within the sec e of the claims.
